Description

6~!753 Cette invention concerne un Eer~ir et, plus particuli~re~ent, un fermoir miniature tel qu'utilis pour attacher dos cha~n~ttes servant au port de bijou~, Il est bien connu en bijouterie d'attacher las d-ux bouts d'une cha~nette port~e ~utour du cou ou du bras au moyen d'Qn fermoir. ~b tels`fermoirs s~nt aussi utiliq~s pour attacher des chalnettes de s6curit~ aux bijoux.
Le fermoir le plus connu commerci~le~ent est cclui en forme d'anneau creux dans lequel est mont~ un plong3ur qui glisse ~ ;
l'intérieur de l'anne~u et se referme dDns un~ extr~mit~ d'~nnoæu au moyen d'un ressort, qui est au88i mont6 dans l'anneau. Ce type de fermoir a cep`endant deo désavatangas maj~urs. Par ~xempla, le plongsur ~t le ressort, qui sont montés ~ l'int6rieur de l'anneau, ne ~ont pas suf~isamment v~ntil~s at se corrodent facilemsnt du ~ l'hu~idit~ de 1~ peDu, L'anneau peut aU8Ji ~tre , facilement apl~ti ou tordu, Il en r6suLte que le plongeur blo~u~
et le fermoir reste ouvert ou ~ moiti~ Eer~é, ce qui peut occ~-si~nner la perte d'un bijou d~ v~leur.
Il existe aUcai un autre type de fermoir en ~orme de pinc~, dont la m~choire est form~e de pluRieur~ paire~ de dents qui se chavauchent pour encercler particlle~ent l'anneau ~ l'extr~mité
de la cha~nette, L'anne~u de la cha~nette peut fàcilement s'accro-cher ~ une seula p~ire de dents et, si une trop forte t~n~io~ est appliqu~e sur la cha~nettc, ladite paire de den~s p~ut ca~æ~r~
Le but de l'invention est donc de pr~voir un fer~oir qui aat completemant s~curitaire et dont le~ compo6antes sont blon exposéas ~ l'alr afin de ne pa3 se corroder facile~ent.
Le fermoir~elon l'invention comporte un pr~iar 61~ent ayant un corps principal et une m~ohoire en forma do crochet reli~e int~grale~ant au corps principal du premier ~l~m-nt, at un deuxieme ~lément ~yant un corps princip~l
6 ~! 753 This invention relates to an Eer ~ ir and, more particularly, a miniature clasp as used to attach back cha ~ n ~ ttes for wearing jewelry ~, It is well known in jewelry to tie the two ends a cha ~ clear port ~ e ~ around the neck or arm by means of Qn clasp. ~ b such clasps are also useful for attaching jewelry security chains.
The most famous clasp commerci ~ the ~ ent is cclui in shape hollow ring in which is mounted ~ a plunger which slides ~;
inside the year ~ u and closes in a ~ extr ~ mit ~ d '~ nnoæu by means of a spring, which is also mounted in the ring. This guy of clasp to however two major disavatangas. By ~ xempla, the plunge ~ t the spring, which are mounted ~ the interior of the ring, have not suf ~ ciently v ~ ntil ~ s at corrodent facilemsnt of ~ the hu ~ idit ~ of 1 ~ peDu, The ring can auU8Ji ~ be, easily flattened or twisted, it follows that the diver blo ~ u ~
and the clasp remains open or ~ half ~ Eer ~ é, which can occ ~ -if ~ nner the loss of a jewel d ~ v ~ their.
There is another type of clasp in ~ pinc elm ~, whose ch ~ is formed of several ~ pair ~ of teeth which capsize to encircle particlle ~ ent the ring ~ the extremity of the net chain, The year ~ of the net chain can easily increase expensive ~ only one p ~ ire of teeth and, if too strong t ~ n ~ io ~ is applied to the chain, said pair of den ~ sp ~ ut ca ~ æ ~ r ~
The object of the invention is therefore to pr ~ see an iron ~ oir which completely safe and whose components are white exposed ~ the alr so that pa3 does not corrode easily ~ ent.

Finalement, la largeur de ch~cune de~ mRchoire~ 14 et 22 e~t telle qua le~ mschoires recouurent une partle sub~tanti~lle de l'~nneau de la cha;nette, ce qui ampêche la déformation de l'an-neau de~ m~choires, m8me 3i une tension considérAble eat subie par la chaine~te, en sa r~ppelant que le8 crochsts sont con~t1tués pr~f~rablement d~un~m~tal pr~cieux malléable, tel qUB l~or, ~t qUe la portion interm~diaire de cheque crochet e~t plus ~paicse que la pointe dudit crochet.
La cavit~ Por~ée par le3 crochets Permés 16 et 24 est -~
de dimension telle que l'annesu est encerclé par le crochet lor3que la cha~nette est tendue. De c0tte f~on, le ~ermnlr ne peut s'ouvrlr parce que las deux crochets 16 st 24 recouvrent des surPace~ oppos~es de J'an~eau et ainsi empêchent le ~ermoir de ~ouvrir. Pour ouvrir le fermoir, il f~ut poua~er l~anneau hor~ des cevit~ formées psr - 4a -les crochets 16 et 24 et ainBi d~bloquèr le f~rmoir.
Les el~ents 10 et 18 sont munis de pattes 36 et 38 perm~ttnnt l'ouverture du fermoir pour d~g~ger l'nnneau, comme illustr6 aux figure~ 2 et 3. La patte 38 est plus longue que la p~tte 36 pour y permettre la fixation d'un nnneau 40 servant ~ rolier le fermoir ~ l'autre extr~mit6 de la cha~netts.qan~ g~ner le ~ouvement de la patte 36. La patta 36 est munie d'une rainure 42 pour y in~rer l'ongle d'un doigt, de faScon ~ f~ciliter l'ouverture du fermoir.
Bien que l'invention ait ~t~ d~crite en se r~f~r~nt ~ une réalisation p~rticuli~re, il e~t bien ent~ndu qu~ des variantes sont aussi envisag~es dans le cadre des revendicatien~ qui suivent.

Ceci est une divulgation suppl~mentaire suits l'invention d~crite ci-haut at intitules "Fermoir"~
Il s'agit d'un,s amélioration apport~e aux crochets 16 et 24 du fermoir. TB1S qulillustr~s dans 1BS dessins dls la divul-gation principale9 ces crochets 16 et 24 ont chacun un bout int~leur asssz pointu. Cette construction particuli~re est un désavantage car il est nécessaire de pousser l'anneau hors des cavité~ ~ormées par les crochets vers le~ pattes 36 et 38 pour fermer le ~ermoirO
Le but de la divulgation supplémentaire est donc de pr~voir un fermoir tel que d~crit ci-haut qui s0 ~ermfl automatique-ment ean~ auoir ~ deplacer l'anneau dls3~ retenu dans l'un des orochats.

This is an additional disclosure suits the invention described above at "Clasps"
This is an improvement made to hooks 16 and 24 of the clasp. TB1S shown in 1BS drawings in the disclosure main gation9 these hooks 16 and 24 each have an end int ~ their sharp asssz. This particular construction is a disadvantage because it is necessary to push the ring out cavities ~ ~ shaped by the hooks towards the ~ legs 36 and 38 to close the ~ ermoirO
The purpose of the additional disclosure is therefore to pr ~ see a clasp as described above which s0 ~ ermfl automatic-ment ean ~ auoir ~ move the ring dls3 ~ retained in one of orochats.
